'This .invention .relates .to .a window .panel c0n 'structionandjmore particularly, vto a wood Vstorm sash vflor a glazed metal sash.

.1t.is an object of this '.inventionfto produce a storm sash of economical construction and which,.at`the.same time, provides a vvery effective as wellas attractiveinsulating means for .a .metal sash. More specifically, the .invention contemplates-a stormsashinthe form of a'woodframe adapted to be attached to a metal sash and an .insertpanelprovided vwith glazing adapted to be removably inserted .within the iframe. Inorder to reduceas much as .possible the .cost .of millwork on theframaas well as the frame members of the insertpanel, the sashfof this invention 'is preferably designed .so that each .of the `frame members for the .insert panel are .of lthe same shape and .size in crosssection. Likewise, each of the side members of .thefframes are of correspending cross section, Vand the .top .and bottom frame members preferably have .the same .cross section.

Figc is an enlarged Yfragmentary sectional view sho-wing theinsert panel seatedinits operative position.

Referring to the drawings, and particularly to Eig. 4, there is illustrated a metal sash Ill of conventional 4design which comprises `a casing I2 at one side of which there is hingedVasby hinges .l-4,.av metal framed window l5.. Casing |2 -is provided with a conventional locking handle i3 and va handle .2li for opening .and closing the window '5.6.

The vstorm sash of this invention -includes an outerwood .frame ,22 which Ais constructed of a pair -of upright stiles 24 and-a ,pair of top and bottom rails 25. Stiles :2.4 are ,milled `sections provided with a `longitudinal stopmember .2.8 on 'theface thereof which-defines theinner .periphery of .frame .22. Top vand bottom arails 26 are likewise `'formed as similarly milled sections. llilaclfi of the rails 26 are fashioned'on-.the face thereof which denes ythe .inner periphery yof frame 22 with a groove 30 'and a stop member'z extending along the inner side of groove 30. Stiles 24 and rails 26 are preferably of thesame size in cross section,y stiles 24 differing from rails ZS only vin the provision of groove 3D. In other words, vstiles 2t can be fashioned `into rails 26 by simply milling therein groove 30. In other respects, the stiles and rails maybe of identical shape and size in cross section.

Outer frame 22 is of a size corresponding to metal sash i6 and is adapted to be fastened against the outer face of sash I6 by mounting screws 34.

Within frame 22 -an insert panel 36 is arranged to be removably secured. Panel 3B is formed with top and bottom frame members 38 and side frame members @D which are secured together 4at their corners to form a substantially rectangular wood frame provided with a glazing M. Frame members ,3% and lil are milled with cross sections of identical shape `and size, thesemembers being different only with respect to their length. Frame members 38 and di! are milled on the one face thereof which denes the outer v periphery of frame 35 with a groove 42 having an'outwardly extending flange M on the `outer side thereof and a tongue t5 on the inner side thereof. The `edge contour of members 38 and @il is to lsome extent complementary to the edge contour of top and bottom rails 2S of the outer frame 22. Or stated differently, when the insert panel 35 is `tted within outer frame 22, tongue -46 is arranged to interiit with groove 3@ vand tongue 48 Vadjacent the .outer face of frame 22 is arranged to intert with groove 32. At the same time, flange dll overlaps and abuts against the outer face .of lrails 2S and the inner face of panel 36 abuts 'against stop vmembers 32.

In order to permit inserting panel 36 within the opening deiined by frame 22, Vthe panel Yis somewhat shorter in height than the effective height ofthe `opening of 'frame 22. The differencein these heightsis illustrated clearly in Fig. 15, Where it will 'be noted that the vertical distance between the ends of tongues i6 is rslightly less than 'the Vertical distance between the Vbottom of groove 38 at the upper end 'of frame 22 and the top face of tongue 4B along the lower end'of frame 22. The distance between the ends -of tongues et; is however greater than the vertical distance "between the ends of tongues 48 so that,

jin order to insert panel 36 within the openingof frame 22, it is necessary to hold the panelin a lposition Ainclined forwardly at itS upper end 'to .theplane offrame .22, Fig.. 4,and1then1push the panel upwardly to interengage groove 42 with tongue 48 at the upper end of frame 22.

Within groove 30 on lower rail 26 there are arranged several screws 50. These screws can be threaded into the wood a greater or lesser extent to thereby control the effective depth of groove 30. The heads of screws 50 are always elevated from the bottom wall of the groove to an extent such that when panel 36 is dropped from the position shown in Fig. 5 to that shown in Fig. 6, tongue 46 at the upper end of the panel is still engaged at least partially within groove 3i] atthe l y upper end of the frame 22.

A pair of clips 52, each having an offset portion 54, are mounted on stiles 24 and arranged to be pivoted such that when panel 36 is arranged Within the opening of frame 22 the offset portions 54 overlie the flange portions 44 and prevent movement of pane1 3G in a direction outwardly of frame 22. Panel 36 is normally prevented from falling out by the interlocking tongue and groove engagement of the respective members of the frame and panel at the upper and lower ends thereof, and clips 52 are provided merely for the purpose of preventing the panel from falling cut of frame 22 should it be accidentally displaced upwardly such as when the window is being Washed. Y

As was described very briefly above when it is desiredrto insert panel 36 within the opening of frame 22, the pane1 is tilted toward the plane of frame 22 at its upper end and then pushed upwardly to engage tongue 48 at the upper end of the frame within groove 42 at the upper end of the panel. Grooves 42 and 30 are, of course, slightly wider than tongues 46 and 48, to permit such interengagement of the tongues with the grooves while panel 3S is in the inclined position. The lower end of panel 36 is then swung inwardly to a position where the inner face of lower frame member 38 abuts against the outer face of stop 32. Panel 35 is then permitted to drop so that it is supported at its lower end upon screws 59.

When panel 36 is arranged within frame 22 in the manner above described, it will .be noted that the iiange portion 44 on frame members 38 and 40 overlap the outer face of frame 22 around the entire frame opening. This arrangement provides not only an effective seal between panel 36 and. frame 22 but also a very attractive construction. It will also be noted that the grooves 3Q on the side frame members 40 do not intergage with a tongue on the stiles 24. These grooves simply provide a vertically extending channel along the vertical edges of panel Sii, which channel provides a passage for rain and moisture that may accumulate between the peripheral edges of the panel and outer frame. In the absence of grooves 30 on the side members 4,0, the moisture accumulating between the edges v of panel 35 and frame 22 would gradually seep into the space between the glazing of the metal sash I6 and the storm window. These grooves therefore have a very important function and, at the same time, enable the milling of the members 38 and 40 with the same cross section. In

other words, both of these members may be out justment often becomes necessary because of 4 shrinkage, expansion, or warping of the wood.

It will thus be seen that I have provided a storm sash construction which is not only economical but also very attractive. The construction furthermore provides a very eiective means for insulating a metal sash and enables the insertion and removal of the insert panel from its outer wood frame to be performed as a very simple operation.

I claim:
